Active clinical trials for "Stomach Neoplasms"

Gastric cancer with peritoneal carcinomatosis has a poor prognosis, with little treatment options available. The current treatment strategy consists of palliative systemic chemotherapy. However, previous research suggests that systemic chemotherapy is less effective against peritoneal carcinomatosis than against metastases that spread hematogenously. Several studies suggested that in patients with peritoneal carcinomatosis, intraperitoneal chemotherapy (IP) may be superior compared to intravenous chemotherapy. Intraperitoneal chemotherapy could lead to higher concentrations of chemotherapy in the peritoneal cavity for a longer period of time, resulting in an increased cumulative exposure to the peritoneal metastases. A few Asian studies have shown promising results with intraperitoneal chemotherapy in patients with peritoneal carcinomatosis of gastric origin. However, intraperitoneal chemotherapy combined with systemic chemotherapy has not been investigated in Western patients with peritoneal carcinomatosis of gastric origin yet. The objective of this trial is to establish the maximum tolerated dose (MTD) of intraperitoneal administration of irinotecan, added to systemic capecitabine/oxaliplatin (CAPOX) in patients with peritoneal carcinomatosis of gastric origin.

This study is an open-label, phase II study with a safety lead-in to assess the response rate of induction olaparib and stereotactic beam radiotherapy (SBRT) followed by combination olaparib/pembrolizumab in patients with metastatic gastric and GEJ cancers after at least one of therapy.

This phase II trial studies how well chemotherapy with or without radiation or surgery works in treating participants with esophageal or gastric cancer that has spread to less than 3 places in the body (oligometastatic). Drugs used in chemotherapy, such as fluorouracil and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Surgery, such as complete surgical resection, may stop the spread of tumor cells by surgically removing organs or tumors. Giving chemotherapy with radiation or surgery may work better than chemotherapy alone in treating participants with oligometastatic esophageal or gastric cancer.

The purpose of the study is to evaluate the efficacy and safety of S-1 plus Oxaliplatin versus S-1 only as adjuvant chemotherapy after curative distal gastrectomy in patients with locally advanced gastric cancer.

The purpose of this study is to explore the safety and feasibility of laparoscopic spleen-preserving No. 10 lymph node dissection for patients with advanced middle or upper third gastric cancer.

This study will investigate the safety and tolerability of ADP-A2M4CD8 T-cell therapy in subjects who have the appropriate human leukocyte antigen (HLA) and MAGE-A4 tumor antigen. Tumor indications include endometrial, esophageal, esophagogastric junction (EGJ), gastric, head and neck, melanoma, non-small cell lung (NSCLC), ovarian or urothelial cancer.

This phase I trial studies the best dose of sonidegib when given together with pembrolizumab and to see how well they work in treating patients with solid tumor that has spread to other places in the body (advanced). Sonidegib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving sonidegib and pembrolizumab may work better than standard treatment in treating patients with advanced solid tumors.

Gastric cancer is a global health issue as the world's fifth most common malignancy and third leading cause of cancer mortality, respectively. Preoperative radiation therapy may improve overall survival (OS) but is seldom used. There is precedent for preoperative chemoradiation, as it is the standard of care for esophageal and gastroesophageal junction tumors. However, reluctance of physicians to prescribe preoperative radiation therapy in gastric cancer may be due to the large treatment fields necessary to account for stomach motion. MR guided radiation therapy (MRgRT) may permit decreased field sizes and more accurate dose delivery. In traditional CT based radiation delivery the same radiation plan is delivered each day without assessment of inter-fraction or intra-fraction motion. MRgRT permits the physician to contour the unique anatomy daily to generate a new plan to account for day to day organ motion. Real-time MR imaging is also used during the treatment so that radiation is only delivered when the tumor is within the pre-specified target area. Thus, MRgRT may overcome traditional barriers of radiation delivery in gastric cancer and improve oncologic outcomes.

RGX-202-01 (ompenaclid) is a Phase 1, first-in-human, dose escalation and expansion study of RGX-202-01 as a single agent and in combination with FOLFIRI +/- bevacizumab. RGX-202-01 is a small molecule inhibitor of the creatine transporter SLC6a8, a novel metabolic target that drives gastrointestinal cancer progression. During the dose escalation stage, multiple doses of orally administered RGX-202-01 with or without FOLFIRI +/- bevacizumab (single agent or combination therapy) will be evaluated in patients with advanced gastrointestinal tumors (i.e., locally advanced and unresectable, or metastatic) who have had PD on available standard systemic therapies or for which there are no standard systemic therapies of relevant clinical impact. In the expansion stage: Patients with colorectal cancer (CRC) RAS Mutant will be treated at the optimal dose.

It is a trial to compare the efficacy and safety of Albumin-bound Paclitaxel plus S-1 versus Oxaliplatin plus S-1 (SOX) as first-line treatment in advanced or recurrent gastric adenocarcinoma.
